Abstract (en)
[origin: EP0747343A1] A polycarboxylate ester unsaturated monomeric compound has the general formula <CHEM> in which R1 is H, -OH, -COOR5 or a group <CHEM> R2 is H, -CH3 or -CH2COOR4, R3 is H, OH or -CH2COOR4, R4 is H, Na, K or -NH4, and R5 is Na, K or -NH4. It yields polymeric compounds having excellent chelating properties and biodegradability making them useful as detergents and dispersing agents.
